Beginning 10 Feb 2021, and thereafter, all Signalizers™<\/strong> will ship with integrated “simulation mode”<\/em><\/strong> capability.<\/p>\n\n\n\n

While in simulation mode<\/strong> \u2013 regardless of whether a flow meter is attached \u2013 the Signalizer will emit a constant 12 milliamps (50%)<\/strong> from its 4-20 milliamp terminal; and it will also emit a continuous 1 Hz pulse<\/strong> from its pulse terminal.<\/p>\n\n\n\n

The simulation feature will allow the SCADA, telemetry, or building automation integrator to exercise and validate his controller’s I\/O interface before<\/em><\/strong> the meter is installed or before a positive flow condition is available.<\/p>\n\n\n\n

In order to activate simulation mode, both dip switches 1 and 2 should be set into the ON position. To exit simulation mode, dip switches 1 and 2 should be reset, according to the type of connected encoder meter:<\/p>\n\n\n\n\n\n\n\n

Also, every Signalizer includes a 249 \u03a9 resistor<\/strong> in the shipping box. The resistor is included as another complimentary troubleshooting tool. For example, if the system integrator’s multimeter does not offer the ability to measure DC current (in order to validate the 4-20mA signal), then he may install the included resistor as a dummy load across the milliamp output terminals in order to measure DC voltage, instead (which is generally easier):<\/p>\n\n\n\n
